Measure off a 20-inch perpendicular from the wall to the outside corner of
each of the two upper legs. (Fig. 3.) Lay a straightedge from mark to mark,
and draw lines across the legs. Reverse the trestle, and do the same with
the legs at the other end. Then turn the trestle on its side, and draw
lines on the other outside faces of the legs, using the lines already made
as guides. If the operation has been carried through accurately, all eight
lines will be in a plane parallel to the top. Cut off the ends of the legs
below the lines, and the trestle is finished.



II. A JOINER'S BENCH.

After finishing his sawing trestle the reader may be willing to undertake a
larger job, the manufacture of a joiner's bench--if he does not already
possess a good article--heavy and rigid enough to stand firm under plane
and hammer.

For the general design and detailed measurements he is referred to Figs. 4
and 5, in which the dimensions of each part are figured clearly. The length
of 5 feet, width of 2 feet (exclusive of the back E), and height of 2 feet
7-1/2 inches will be found a good average. If the legs prove a bit long for
some readers, it is a simple matter to lay a plank beside the bench to
raise the (human) feet an inch or two.

In order to give rigidity, the struts S1S2 of the trestles at the end and
the braces DD on the front are "halved" where they overlap the legs and
front so as to offer the resistance of a "shoulder" to any thrust.
